WINnOw REGULATOR.

Application filed May 4,

This invention relates to devices foropening and closing windows and although it is not to be so limited it is particularly adapted in its application to the windows in v ehicles, such as in closed automobiles, wherein the window is slidable vertically into and out of a suitable window welll Q The principal' object of the invention is the production of a window regulator of the i above character' which shall be simple in constri'iction7` easy of installation and which shall operate to effectively' raise or lower the window with little manual effort.

Other and further objects of the invention will appear from the accompanying description, the invention consisting in the novel window regulator hereinafter more particularly described and then specified in the claims.

In the accompanying drawings illustrating a practical embodiment of the invention:

Fig. 1 is a front elevation of a" fragmentary portion of a window frame showing the inventionapplied thereto.

Fig. 2 is a horizontal section on the line 2 2 of Fig. 1. v n

Fig. 3 is a horizontal section on the line 3 3 of Fig. 4.

F ig. 4 is an enlarged front elevation of the window regulator showing its position with the window in raised position.

Fig. 5 is a horizontal section on. the `line 5 5 of Fig. 4.

F ig. 6 is a vertical cross-section on 6 6 of Fig. 4.

Referring in detail to the several figures of the drawing:

1 indicates the side members of a rectangular frame which if so desired may be the frame of a vehicle door and which members are provided with inner and outer walls 2 and 3 respectively extending thereacross approximately from their central portions to their lower ends to form a window well. 4 indicates a window or sash which is slidable into and out of said window wellv in suitable guideways or channels 5 formed in said side members.'

The body of a supporting bracket is indicated at 6 and is provided with perforated ears 7 whereby said body may be detachably secured within the window well to the inner wall 2 by suitable screws or bolts as shown in Fig. 3. The body of said the line 19,25. Serial' No. 937,646.

bracket is provided with arvertical slot 7 communicating` with a' larger verticalopenfing 8 and it is also` provided with a slot or opening 9 in a side wall thereof. Secured to an outer wall of said; body, as by the screws shown in Fig. 3 is a fixed rack 10.

11 and 12 indicate small and large gears respectively which are loosely mounted on a shaft 13 but which are fixed or pinned together by suitable pins as shown in Fig. 3 and are adapted to ride within the opening 8. One end of said shaft. carries a guide roller 14 adapted to ride in and be guided by the walls of the opening or slot 7 while the other end is provided with a roller 15 received by a tit-shaped channel member 1.6 secured in any desirable manner to the lower edge of the window 4. v

17 indicates a movable rack whichy ha teeth on both of the opposite sides thereof and which is slidably supportedk intermediate the fixed rack 10 and a: portion of the body G of the `supporting bracket. Ther teeth on' one vside of the movable rack mesh with the smalll gear 11 rwhile the-fixed rackA 10 meshes with the large gear 12. 18 indie' cates a shaft which is suitably mounted in the body of the supporting bracket, one end of which extends into the slot 9y and carries thereon av pinion 19 which meshes with the teeth on the other side of the movable rack 17 while the other end extends through the inner wall 2 and carries thereon a rotatable crank or handle 20.

To raise or lower the window the crank or handle 20 is rotated, motion then being transmitted through the shaft 18 to the pinion 19 through the movable rack 17 which is of a length shorter than the distance of travel of the window, gears 11 and 12 and roller 15 which rides in the channel 16 as has been described whereby the window is either `pushed Vdownwardly in its guideways into the window well or pushed upwardly out of the window well as the case may be depending `on the vdirection of rotation given said crank or handle; Inasmuch as the roller 14 rides in the slot or opening 7 a lateral movement of the shaft 13 is thereby prevented.

When the crank or handle 2O is rotated to i effect a movement of the window in the inanner described the gears 11 and 12,. asy is obvious, will lmove in the saine direction as the movable rack 17 but at a materially greater speed and hence a greater distance so that it requires a relatively slight rotation of said v crank or handle toeffect a movement ot the Window an appreciable amount. L'llo assist in the raising operation of the Window We have provided a counterbalance coiled spring 21 one end of which is secured to a hook 22 carried by the bracket 6 While the other end is secured to a hook or eye 23 fastened in any manner to the movable rack 17.

What We claim as our invention is l. In a Window regulator, a movable rack and a tix-ed rack, a pair of movable gears connected together and meshing with said racks, Vmeans movable with said gears and engaging the Windev7 and means for actuat-v ing said movable rack.

2. In a Window regulator, a movable rack having teeth on tivo sides thereof, a gear meshing With one side ot said rack and conneetedto the Windoma pinion meshing With the other side ot said rack and means for rotating said pinion.

3. In a Window regulator, a supporting bracket provided with an opening therein, a movable raok and a i'ixed rack Within said opening, a pair of rotatable gears movable vertically in said opening and meshing with said racks'and means connecting said gears and the Window and means for moving said movable rack.

4. In a Windoiv regulator, a movable rack and a fixed rack, a small gear meshing With said movable rack, a larger gear meshing with said fixed rack, means connecting said gears and the window and adapted to move YWith said gears and means for actuating said movable rack.

5. In a Window regulator, a movable rack and a fixed rack, a small gear meshing With said movable rack, a larger gear meshing with said fixed rack, said gears being con nected together, means connecting said gears and the window and adapted to move vertically with said gears and means for moving said movable rack.

6. In a Windovv regulator, a movable rack and a'iiiled rack, a small gear meshing with said movable rack, a larger gear meshing with said iiXed rack, said gears being connected together, a shaft extending loosely through said gears and engaging the Window, a pinion meshing with said movabl-e rack and a crank for rotating said pinion.

7. In a Window regulator, a supporting bracket provided with a slot therein, a movable rack and a lined rack, a small gear meshing with said movable rack, a larger gear meshing with said lined raok, said gears being connected together, a shaft extending loosely through said gears and operatively engaging the Window and extending Within said slot, a pinion meshing With saidmovable rack and a crank for rotating said pinion.

8. In a Window regulator, a stationary rack, a movable rack, an operating handle for moving said movable rack, means operatively connected with said window and engagea-ble With said racks and spring means connected with said movable rack for counterbalancing the Weight of said Window.
